Abstract

Input image data is divided into blocks so as to make adjacent blocks partially overlap image data, and the divided image data is filtered in the unit of block. An image processing apparatus and method are provided which can process image data of an arbitrary size at high speed independently from the capacity of a buffer memory, and a computer readable storage medium is provided which stores a program realizing such a method.
